Proposed Subdivision
1 George Tewantin




        4. CONCEPT DESIGN FOR WATER AND SEWER

    In regard to the sewer service we are able to command all of the new lots using a
    gravity sewer system connecting to an existing sewer manhole in George St. To
    avoid trenching adjacent significant trees along the frontage on George St we have
    elected to take the sewer down the side boundary of lot 1 (in the balance lot) on an
    alignment that avoids any existing significant trees. At the back of lot 1 the sewer
    then traverses the rear of the lots fronting George Street to service these lots
    avoiding significant trees. The battle-axe lots are serviced by two sections of sewer,
    one along the side boundary of lot 2 and the other between lots 8 & 9, again
    avoiding existing significant trees. The proposed sewer system has been forwarded
    to Unitywater for initial comment.

    In order to avoid disturbance of significant trees at the George Street frontage the
    water service to each block has been positioned accordingly. Two road crossings
    are proposed to avoid the trenching in front of a large tree in the front of proposed
    lot 1 and lot 10. Note a similar approach is proposed for the underground electrical
    service.

    The above information is provided in support of the response to Council’s
    information request dated 26 November 2014.
